在Flask 项目中使用 MQTT,可以通过使用 MQTT 客户端库进行集成。首先,你需要在你的项目中安装 MQTT 客户端库,例如 Paho MQTT。然后,你可以创建一个 MQTT 客户端,并与 MQTT 代理建立连接。在 Flask 项目中,你可以使用 Flask 的扩展来简化 MQTT 客户端的创建和管理过程。一旦连接建立成功,你就可以使用 MQTT 的发...

We can handle successful or failed MQTT connections in this callback function, and this example will subscribe to the /flask/mqtt topic after a successful connection. @mqtt_client.on_connect() def handle_connect(client, userdata, flags, rc): if rc == 0: print('Connected successfully') mqtt...
因为有项目需求,所以需要flask + mqtt进行联动,因为需要一直开启监听,所以需要一直挂在一个线程上,一开始想到用多线程做,或者说用异步协程来做,后来发现有一个关于flask的mqtt扩展库,因此为了快速上手,直接用该库进行开发,可以节省很多精力。 link: https://github.com/stlehmann/Flask-MQTT 首先,我们需要安装flask...

MQTT is a machine-to-machine (M2M)/”Internet of Things” (IoT) protocol which is designed as a lightweight publish/subscribe messaging transport. It comes very handy when trying to connect multiple IoT devices with each other or monitor and control these devices from one or multiple clients....
Flask是一个轻量级的Python Web框架,它可以帮助开发者快速构建Web应用程序。curl是一个命令行工具,用于发送HTTP请求。JSON是一种轻量级的数据交换格式,常用于前后端数据传输。图像是一种包含图形或图像的二进制数据。 在Flask中,可以使用curl发送包含图像数据的JSON负载。具体步骤如下: 首先,需要安装Flask和curl的相关依...

An alternative manual HTTP testing you could use Swagger, for example for users crud operations in a browser open: http://localhost:81/apidocs to see the Swagger UI and to perform test requests from there! For the MQTT application we'll use mosquitto cli: To install mosquitto cli in Debian...
